Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33615280, here are decompositions:

11 + 33615269 = 33615280
59 + 33615221 = 33615280
131 + 33615149 = 33615280
263 + 33615017 = 33615280
311 + 33614969 = 33615280
317 + 33614963 = 33615280
383 + 33614897 = 33615280
683 + 33614597 = 33615280

Showing the first eight; more decompositions exist.
